I'm using Xiia Live Pro since many monthes. It works like a charm. Every time I get into my car it opens and starts playing my favourite Internet radio station.
Today I'm trying Android Auto and it has an specific icon for audio playing that only shows Google and Google play music.
It also has an Android Auto Apps option, but I could not find the way to add Xiia Live Pro to Android Auto.
I think this is a desireable future.
